A mounting of the class described comprisin I have arranged t e m u ti s a t e ing, an internal combustion engine, a support rear end 01 h n ine, one in advance of the including side frame members and a cross memher, a front engine connection between said engine and said cross member, and lateral connections at the rear of said engine between said engine and said side frame members, one of said lateral connections being in advance of the other of said lateral connections.

2. A mounting of the class described comprising, an internal combustion engine, a support including side frame members and a cross member, a front engine connection between said engine and said cross member, and resilient lateral connections at the rear of said engine be tween said engine and said side frame members, one of said lateral connections being in advance of the other of .said lateral connections.

3. A mounting of the class described comprising, an internal combustion engine, a support including side frame members and a front cross .member, a single front engine connection between said engine and said support, said connection being arranged at one side of the center of gravity of the engine between side frame members, and lateral connections between said engine and said side frame members.

4. A mounting of the class described com prising, an internal combustion engine, a support including side frame members and a front cross member, a single front engine connection between said engine and said cross member, said connection being arranged at one side of the longitudinal center of the engine between said sideframe members, and lateral connections between said engine and said side frame members, one of said lateral connections being in advance of the other of said lateral connections.

5. The combination of an internal combustion engine unit, laterally spaced resilient mounting members interposed between said unit and said supporting structure adjacent one transverse plane of said unit,-and a single resilient mounting member spaced longitudinally from said laterally spaced mounting members and located between the central vertical plane of said unit and one side of said supporting structure and so constructed and arranged as to sustain, in conjunction with only one of said laterally spaced mounting members, the major portion of the weight of said unit, the other of said laterally spaced mounting members being relieved of the major portion of the weight of said unit so as to condition it for opposing oscillatory movement of the unit and predetermining the natural frequency of such oscillatory movement at a comparatively low value.

6. The combination of an internal combustion engine unit, laterally spaced resilient rear mounting members interposed between said unit and said supporting structure, and a resilient front mounting member located between the central vertical plane of said unit and one side of said supporting structure and so constructed and arranged as to sustain, in conjunction with only one of said rear mounting members, the major portion of the weight of said unit, the other rear mounting member being relieved of the major portion of the weight of said unit so as to condition it for opposing oscillatory movement of the unit and predetermining the natural frequency of such oscillatory movement at a selected comparatively low value.
